Synthesizing copies of these genes, or segments of DNA (deoxyribonucleic acid), was difficult enough. But much harder was the job of getting the genetic instructions inside the potential bacterial factory, a weakened lab strain of the intestinal microbe Escherichia coli. The scientists resorted to a little molecular chicanery. Using their new gene-splicing or recombinant DNA techniques, they hitched their two synthetic insulin genes individually to one of the bacterium's own genes. Then they inserted both the synthetic and the natural material into fresh E. coli. As a result, E. coli's DNA-reading machinery was unable...
